The not-planets

Emily Lakdawalla • July 14, 2015 • 38

Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.

Adding Churyumov-Gerasimenko to my scale comparison of comets and asteroids

Emily Lakdawalla • March 13, 2015 • 4

Having found a color photo of the comet, I finally added Churyumov-Gerasimenko to my scale comparison of comets and asteroids visited by spacecraft.

New Rosetta view of the comet - and a comparison to other comets

Emily Lakdawalla • July 31, 2014 • 8

Rosetta's view of the comet is getting better and better. Today they released a new image from the high-resolution OSIRIS camera, and it's a very fresh one, taken only two days ago. Distinct features are coming into view. And it's finally detailed enough for me to compare it to the five other comets we've visited in the past.

A close look at Saturn's closest moons

Emily Lakdawalla • June 26, 2014 • 1

A new composite image of the eight named moons that orbit closest to Saturn, and a list of all the best Cassini observations of these moons.

Intro Astronomy Class 6: Mars (continued) and Asteroids

Continue exploring Mars and learn about asteroids in this video of class 6 of Bruce Betts' Introduction to Planetary Science and Astronomy class.

2015 will be the Year of the Dwarf Planet, and you need to tell people about it!

Emily Lakdawalla • March 05, 2014 • 11

I am very excited about 2015, more so than I have been about any year since I started working at The Planetary Society. Dawn will enter orbit at Ceres, and New Horizons, which will fly past Pluto and Charon. But if we want this kind of exploration to continue, I'm challenging you, dear readers, to tell the world why such non-planetary worlds are compelling places to go exploring.

New names for Pluto's little moons Kerberos and Styx; and a new moon for Neptune

Emily Lakdawalla • July 15, 2013 • 5

Pluto's moons, formerly known as "P4" and "P5," are now named Kerberos and Styx; I thought I'd help place them into context with a little help from Cassini. Also, Neptune now has a 14th known moon.

Scale comparisons of the solar system's major moons

Emily Lakdawalla • July 10, 2013 • 15

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

My ever-popular asteroids-and-comets montage, now in color, with bonus Toutatis

Emily Lakdawalla • December 18, 2012 • 9

My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

Cheat sheets for Vesta's craters and Dawn's Vesta timeline

Emily Lakdawalla • April 19, 2012

I made myself a cheat sheet to many of Vesta's distinctive-looking craters, and also wrote down a list of the major dates in the timeline of Dawn's exploration of Vesta.
